' and artificial, and any and all combinations of the foregoing or any other nutrient material in any state, or condition or with inert materials such as-water, sand, or any other substances which may be used other than as nutrients. In addition to the above, roughages and forages, ensilages, legumes, hays,

and by-products of the vegetable oil industries may be used in combinations or mixtures with calcium gluconate as a stock feed.

Calcium gluconate may be used alone or in the above mixtures as a satisfactory source of calcium for-young and mature poultry. Experience has shown that hens having a high annual egg production have a tendency to lay eggs with shells which are thin and of poor texture, especially during the maximum I production period. We have found that if such hens are fed feeds composed wholly or in part of calcium 'gluconate, the shells of the eggs then produced are of good quality and texture.

We claim: 1. A feed consisting solely of calcium gluconate.

0 2. A feed including calcium gluconate as 7 its essential ingredient.

Example 2."We fed a mash containing calcium gluconate and other nutrient ingredients such as a standard poultry feed to hens previously laying eggs with shells which were thin and poor in texture, and noted a marked improvement in the thickness and texture of the shells of the eggs laid by such hens shortly thereafter. The meaning of the word feed .as now 4 used by animal husbandmen and students of animal nutrition is the same as that of food with the restriction that feed be used when
